Abstract

A process for making a carbon nanotube structure includes forming a composite by depositing or growing carbon nanotubes onto a metal substrate, and infusing the carbon nanotubes. In other aspects, a method of making a wire, includes coating carbon nanotubes on a wire, and electroplating the carbon nanotubes. In still other aspects, a method of making a conductor includes growing or depositing vertically aligned carbon nanotubes on a sheet. Yet still, a method of making a cable includes forming multiple composite wires, each composite wire formed by depositing or growing carbon nanotubes onto a metal substrate, and performing a metal infusion of the carbon nanotubes. The method also comprises combining multiple finished composite wires or objects to make large cables or straps.
